Question

Find the measures of two angles, one positive and one negative, that are coterminal with pi divided by five. How do you do this? :/

Answer 1

`\theta= (\pi)/(5)`

`\\ \theta_1,\theta_2` - coterminal angles


`\\ \theta_1= (\pi)/(5) +2\pi= (\pi)/(5) + (10\pi)/(5)= (11\pi)/(5) \\ \\ \theta_2= (\pi)/(5) -2\pi= (\pi)/(5) - (10\pi)/(5)=- (9\pi)/(5)`
